Using Populus feedstocks for biofuels, bioenergy, and bioproducts is becoming economically feasible as global fossil fuel prices increase. Maximizing Populus biomass production across regional landscapes largely depends on understanding genotype × environment interactions, given broad genetic variation at strategic (genomic group) and operational (clone) levels. A regional network of Populus field tests was established in the Midwest USA in 1995, 1997, and 2000 to assess relative productivity of 187 clones grown at Westport, Minnesota; Waseca, Minnesota (only 2000); Arlington, Wisconsin; and Ames, Iowa. We evaluated biomass potential throughout plantation development and identified clones with yield substantially greater than commercial controls (Eugenei, NM6).
